The only thing that is on your cat that is backwards…the spines on its rough tongue. The spines on your cat’s tongue needs to be facing backwards in order to provide your cat with that effective comb to be able to groom its fur thoroughly. Your cat uses its moist tongue to pull on its fur as if to comb it out and then proceeds to lick it to moisten it, then combs it out again.

This process of grooming is time-consuming and it is obviously why your cat cannot groom its entire body in one single grooming session. It actually takes days for your cat to groom every inch of its body, with the exception of its unreachable chin. Go here, to the site for the veterinarian Linda Vista.
